No the answer is not A the answer it C. the bacterial cells to maintain homeostatic
There are no natural predators of rabbits in Australia, so they are able to reproduce at an alarming rate unharmed. In the US however, there are foxes and other animals that prey on rabbits, which helps keep the rabbit population lower.
Answer:
the frequency of the resistant allele after one generation is 0.989
Explanation:
Given that :
A farmer plants Bt cotton that is genetically modified to produce its own insecticide.
Of the cotton bollworms feeding on these Bt plants, only 5% survive
i.e the survival rate s = 5% =0.05
unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide
Frequency of R allele = 0.01
In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.
According to Hardy-Weinberg Equilibrium ;
p+q = 1
Let p = R and q = r
R + r = 1
0.01 + r = 1
r = 1 - 0.01
r = 0.99
Now; the frequency of the resistance allele after one generation can be calculated as :

where ;
q' = R
q = r



q' = 0.989
Thus; the frequency of the resistant allele after one generation is 0.989
Answer:
2 : 1
Explanation:
- The surface area of the cube;
Area of one (1) side * 6 sides = 3 *3 * 6 = 54 cm²
Length * Width * Height = 3 * 3 * 3 = 27 cm³
- Surface area – to – volume ratio;
54 : 27 = 2 : 1
